Abstract :
The feasibility of combined current leads with a superconducting extension using high-Tc superconductors is demonstrated. The performance of systems with heatsink at room temperature or at LN2 temperature are compared. In both cases the leads and the busbars are cooled by counterflowing helium gas and the superconducting part can be, depending on T and I, in the superconducting state, in the normal state, or in the current-sharing regime. The improvement obtained by such a system is important notwithstanding the limited current capacity of today high-Tc superconductors, at least for the LN2 -cooled system
